Hydrogen Detected in Ramsay 2 Well
Highlights:
- Ramsay 2 spudded on Friday 17 November 2023, with surface casing set at 192m over the
weekend.
- Hydrogen has so far been detected across the entire Parara Limestone section.
- With Hydrogen shows from shallow depths, wireline logs were run in the first 100m of the
well below the surface casing, with MDT samples also recovered.
- MDT samples and other preliminary mud gas samples are being sent to a third-party lab for
analysis.
- Further updates will be provided in due course following analysis of samples.
Further to previous market releases regarding its flagship Ramsay Natural Hydrogen Project, the Directors
of Gold Hydrogen Limited (Gold Hydrogen, ASX: GHY, the Company) are pleased to provide a preliminary
operational update on the Ramsay 2 well.
Drilling at Ramsay 2 commenced on 17 November 2023, this being the second dedicated natural hydrogen
exploration well in Australia, and a follow up to the successful Ramsay 1 well. Over the weekend, the
surface casing on Ramsay 2 was set at 192m, in the top of the Parara Limestone. Hydrogen was measured
in the mud gas from the commencement of drilling out of the surface casing at shallow levels of 192m,
and has continued to be detected across selected zones within the Cambrian limestone section, with a
current drilling depth of approximately 700m. Due to the encouraging signs of Hydrogen the decision was
made to stop drilling at 290m and conduct wireline logs to obtain downhole reservoir samples to that
depth. During this logging run, four (4) down hole samples were recovered to surface and preliminary
analysis show elevated hydrogen levels in the gas recovered from the MDT sample from 201mMD. Drilling
then recommenced, with an expected TD of the well early next week at a depth of approximately 1,100m.
Further wireline logs will be obtained following well TD.
In addition to these down hole samples, numerous mud gas samples have been taken during drilling via
the mud logging system with all samples being progressively transferred to a third-party lab for testing.
Results of the testing will be received over the coming weeks, and once they are fully completed and
interpreted, a further market update will be made.
Although the results are only preliminary and indicative, Ramsay 2 has confirmed the presence of
Hydrogen as found in Ramsay 1 and the historical Ramsay Oil Bore. This further supports the view of the
Company that there is a natural hydrogen accumulation in the area.
Gold Hydrogen Managing Director, Neil McDonald said: “The MDT results are exciting for us as it
demonstrates that the limestone has suitable porosity and permeability to allow natural hydrogen to be
produced. Although early days, this result is likely to lead to Australia’s first natural hydrogen discovery.”
It is important to note that there remain both geological and potential development risks associated with
the Ramsay Project and the Company’s commercial and business objectives. These risks relate to the
presence, recovery and potential volumes of hydrogen, but also due to the location of the resource within
agricultural areas and the proximity to National Parks on both Yorke Peninsula and Kangaroo Island,
requiring significant landholder and community engagement. The worldwide, Federal and South Australian
Government and industry efforts to secure hydrogen as an alternative energy source provides confidence
that any technical and social concerns may be overcome.
